The Classical Gravitational N-Body Problem
Douglas C. Heggie
Let a number, N, of particles interact classically through Newton's Laws of Motion and Newton's inverse square Law of Gravitation. The resulting equations of motion provide an appr…
The Gravitational Million-Body Problem
Douglas C. Heggie
We review what has been learned recently using N-body simulations about the evolution of globular clusters. While simulations of star clusters have become more realistic, and now i…
Two collaborative experiments in star cluster evolution
Douglas C. Heggie
We summarise the specification and some previously unpublished results of the collaborative experiment (``KyotoI'') that was carried out at the time of the Kyoto General Assembly o…
Escape in Hill's Problem
Douglas C Heggie
This didactic paper is motivated by the problem of understanding how stars escape from globular star clusters. One formulation of this problem is known, in dynamical astronomy, as…
Mass Loss from Globular Clusters
Douglas C. Heggie
We consider both observational and theoretical issues related to dynamical mass loss from the old globular star clusters of the Galaxy. On the observational side the evidence inclu…
Dynamical Simulations: Methods and Comparisons
D. C. Heggie, M. Giersz, R. Spurzem +1
We review recent progress in computational methods for studying the dynamical evolution of large star clusters. After describing some highlights of a new comparison of different mo…
